I like my Capstone 550. It does feel a little cheap, but I believe the OEM is Super Flower and I have had zero problems with it. I also have a pair of Rosewill RG530 units that are made by ATNG and are only minimum 80Plus efficiency, but they work fine.

What's the affect of overclocking gpus while crunching? Mine are slightly overclocked.

Since you have those watercooled, I would say as long as your clocks & temps are stable (and that EK rad is doing enough for you), you should be good. However, if your clocks are not stable, you might find out by running WCG on them.

I already saw that the clocks that are completely stable in gaming weren't yesterday, had 2 drivers crash and recover yesterday afternoon. I've since dropped clocks to 1000/1475 and its been fine since last night ~7pm, ran it all night since

Yeah you want to get the drivers/cards stable. Wcg will show you if they are stable or not. Thing can go for a few days and run perfect then all of a sudden you start have driver crashes and such. I was getting them on the Cfed 6850 rig at stock clocks. It gamed perfect but wcg found something it didn't like. I ended up doing a complete driver sweep and backing down to the 12.6 cats and it's been smooth sailing since.

KieX is getting ~100k between the three. So I figure I can get 30-33k from it--and then probably a few more K from the CPU

After a few days of running they seems to be averaging 31K each. But not sure if that's accurate either. Have over 52pages of pending validiation.. and loads of those are waiting for the wingman to return their completed WU.. some as old as 10/23 :shadedshu

I got app_info to work but only for 4-5 hours each time. I always ended up with a rig without GPU WUs in the morning. Only thing I didn't try is the patch that sends WU when they are completed. Maybe that would make the all important difference. Didn't try the multi-bonic yet.
